AV receiver cannot play multichannel DSD if sourced using their networking capabilities or if sourced via their USB inputs. The only input multichannel DSD can can be accessed via is via a receiver's HDMI inputs. DSD and DSF via a receiver's networking abilities and USB inputs is restricted to 2 channel stereo. The same goes for multichannel FLAC and or any other multichannel audio format. It is stereo only and a maximum of 2 channels if wanting to access audio via any AV receiver networking capabilities.

The solution is to access the files using an external media player and use that player to play the files. The external media player would then need to be connected to the AV receiver via HDMI in order to convey the resulting multichannel DSD or PCM to the receiver.

No AV receiver facilitates playing multichannel audio accessed via either their networking abilities or via their USB inputs. THese two interfaces are restricted to stereo audio. This includes the Denon AVRX7200.

Not really. I can only guess that it has to do with the signal paths. The USB inputs usually relies upon the same board used for a receiver's networking hence why both are subject to the same restrictions. This also suggests that the audio accessed in conjunction with that board is subject to a different decoder than that associated with the receivers other digital inputs? The DAC will be the same DAC, but the signal path to that DAC will differ for the networking board when compared to the HDMI board for example. I'm quessing the signal paths are only stereo in nature so audio is therefore restricted to 2 channels?

Anyway, for whatever reason, AV receiver do not handle and cannot play multichannel audio accessed via their networking abilities.

I was hoping for a straight NAS to receiver solution without having to go through an intermediate player and HDMI.

What about devices you currently have connected to the receiver via HDMI. Do any of these have inbuilt DLNA networking and the ability to play the files in question? Some Blu-ray players include such abilities.
